摘要：

In order to improve the adsorption performance of phenolic resin based activated carbon fibers, the high-ortho phenolic resin was catalyzed by zinc acetate and sulphuric acid, and then mixed with polyvinyl butyral(PVB)as raw material, the flexible high-ortho phenolic resin based activated carbon nanofibers were prepared by a sequence of processes, including electrospinning, consolidation, carbonization and activation, and then the structure and performance were tested and analyzed by Fourier infrared spectrum, scanning electron microscopy, thermogravimetric analysis and specific surface area and pore size distribution analyzer. The results show that the crosslinking structures of the phenolic fibers are formed with the increase of the char yield, and the thermal stability at low temperature decreases with the alcoholysis of PVB. The adsorbing evaluation demonstrates that the high specific surface area of the high-ortho phenolic resin based activated carbon nanofiber reaches 1 409 m2/g, and its adsorption capacity for methylene blue and iodine appears as high as 837 and 2 641 mg/g, respectively.
